Abstract

Fe–Cu bimetallic oxide nanoparticles supported on silica gel that catalyze the hydrogenation of nitrobenzene to aniline and of dinitrobenzenes to phenylenediamines under relatively mild reaction conditions (200°C, \({{p}_{{{{{\text{H}}}_{2}}}}}\) 1.3 MPa, 4 h, and 700 rpm) are synthesized. The catalytic properties of supported bimetallic Fe–Cu catalysts depend on the synthesis procedure, sample composition, and conditions of thermal treatment. There is a synergistic effect of interaction between Cu and Fe in the hydrogenation of nitrobenzene, 1,3-dinitrobenzene, and 1,4-dinitrobenzene in the presence of a bimetallic Fe–Cu catalyst obtained via coprecipitation.

Fe-Cu纳米粒子存在下芳香硝基化合物的选择性液相加氢

摘要

Fe-Cu双金属氧化物纳米粒子负载在硅胶上，可在相对温和的反应条件下（200°C，催化硝基苯氢化成苯胺，二硝基苯氢化成苯二胺），\（{{p} _ {{{{\ text {H} }} _ {2}}}}}）），合成了1.3 MPa，4 h和700 rpm。负载型双金属Fe-Cu催化剂的催化性能取决于合成程序，样品组成和热处理条件。在通过共沉淀获得的双金属Fe-Cu催化剂存在下，铜和铁之间的相互作用在硝基苯，1,3-二硝基苯和1,4-二硝基苯的氢化中具有协同作用。
